GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 407,931, dated July 30,1889.

Application filed May 6, 1889. Serial No. 309,695. (No model.)

To all whom it may concern.-

Beit known thatl, CHARLES J. HIRLIMANN, a citizen of the United States,residing in Fort Lee, in the county of Bergen and State of New Jersey,have invented certaiu'new and useful Improvements in Galvanic Batteries,of which the following is a specifica tion.

My invention relates to galvanic batteries, the object being to providea cheap and. efficient carbon battery.

In general terms, the invention consists of two carbon boxes orrectangular structures, one placed within the other, and the two beingjoined together at one end, thus forming a chamber or receptacle betweenthe outer and inner boxes. A free passage is left through the inner box.The outer box is formed with two cars projecting above the mouth of thejar or cell, in which are fitted binding-posts for making connections.Any usual depolarizing agent is placed in the chamber between the twoboxes and sealed in by wax or in any other suitable manner. The whole isthen placed in a suitable jar, preferably rectangular in shape, and

containing the electrolyte.

Referring to the accompanying drawings, Figure 1 represents aperspective view of the carbon boxes. Fig. 2 represents a centralsection of a complete cell, and Fig. 3 represents a plan of the coverused for sealing the cell.

The containing-jar is represented by A.

B represents the carbon element of the battery. It consists of tworectangular carbon boxes I) and I). These boxes are placed one withinthe other, and are joined together at the bottom, as shown in Fig. 2,thus forming a receptacle b between the Walls of the.

two boxes. In this receptacle I place any suitable depolarizing agent.This depolarizing material is sealed in by means of a layer of wax orparaffine, (represented by 11 Airholes I) through the wax may beprovided, if desired. The chamber inclosed by the inner box is open atboth ends, and is adapted to receive the zinc pencil O. The zinc is heldout of contact with the carbon by the cover on of the jar, which may beof glass or any other insulating material. The inner box may also havelateral perforations, as shown.

The outer carbon box is formed with two of the jar, and the cover m iscut away, as

shown, so as to embrace the ears 9?. n and entirely cover the cell.

Having thus described my invention, I claim 1. In a galvanic-batterycell, a carbon element consistingof two rectangular carbon boxes, oneplaced within the other, and the two connected together at one end.

2. In a galvanic-battery cell, a carbon element consisting of tworectangular carbon boxes, one placed within the other, and the twoconnected together at one end, afree passage or chamber being providedthroughout the inner box.

3. In a galvanic-battery cell, a carbon element consisting of tworectangular carbon boxes, one placed within the other, and the twoconnected together at one end, thus forming a chamber between the twoboxes, in combination with a depolarizing agent placed within thechamber.

a. In a galvanic-battery cell, a carbon element consisting of tworectangular carbon boxes, one placed within the other, and the twoconnected together at one end,'a free passage or chamber being providedthroughout the inner box, in combination with a zinc element occupyingsaid chamber.

5. In a galvanic battery, a carbon element having a rectangular shape,and provided with two cars extending above the mouth of the cell, incombination with an outer rectangular jar and a cover for the same, thelat ter having cut-away portions to accommodate the ears on the carbonelement.

In witness whereof I have hereunto signed my name in the presence of twosubscribin witnesses.

CHARLES J. HIRLIMANN.
